Re: Bevel drive nasty!

So as Bill had said earlier, there is a lot of tiny metallic shards in your timing case (as a result of your gear destruction) and these will of course have 'got everywhere' in your motor, i'm sure you don't want to take the whole bl**dy engine to bits to clean it out, but at least if you remove the primary drive side cover (which is easy) and remove the clutch (easy) and alternator flywheel (which needs an extractor) you will then get better access to your 'other' main bearing (you already have access to the timing side bearing) you can then wash out both bearings with a solvent to get rid of the oil which will allow you better to determine crankshaft end float. Ideally if you have (or can get a hold of) a dial test indicator mounting it on a temporary bit of sturdy steel plate bolted to the crankcase face you then can properly measure the crankshaft end float. If you do get a DTI, set it up to measure the crankshaft run out which if excessive will make setting up your 'new' bevels problematic and could also be the culprit for your current damage?
The more 'bits' you can get off the crankcases the more chance you have of getting the debris out with a really good wash. and when you rebuild make sure to fit a magnet onto the oil filler dipstick which should catch any 'floating stuff'. If you decide to take the head and barrel off then get the crankshaft sludge trap screw out and get the cavity cleaned out too.
There are so many reasons that could be responsible for your damage your best way forward is to assume nothing is correct and as much as possible start from scratch again........crank endfloat first.
